Rosny College Computer Graphics & Design 2015: Project & Graphic Skills 1 – Design An Energy Drink Product A Guide To The Production Process: Part One – Modelling the Drink Can

PART ONE

Modelling The Drink Can Part one of the design process involves the creating the can for the energy drink using polygon modelling methods. This method is the basic building technique for accurate and detailed 3D objects. The polygon modelling techniques most used here will be Chamfer, Extrude, Bevel and Inset. Modifiers like Turbo Smooth and Shell will also be used to add extra detail to the can. You will work with polygons, edges and vertices as you create the can.

This type of 3D polygon modelling is called hard surface poly modelling as distinct from free‐form organic poly modelling which is more appropriate for characters with a skin and clothing.

Step 1 – Getting Started

Open 3DS MAX 2015. When then New Scene dialog opens, set a project folder in one of your College drives by creating a project folder called “energy can”. Then click the Create New Scene button. Once the scene is created, save it in the Scenes sub folder of the new project folder with a name such as “energy can”.

Step 2 – Set Up Units

Open 3DS MAX 2015. Go to the Customize > Units Set Up drop down menu and Set Units to Millimetres in order to make sure you will have a physically accurate drink can.

Step 3 – Create A Cylinder

From Create > Geometry create a Cylinder with the Height of 140mm and the Radius of 30mm in the Perspective viewport. Right click on the Cylinder and select Convert to > Convert to Editable Poly. Name the Object “drink can”.

* NOTE In a 3D graphics application it is very important to properly name everything in order to keep track of the many

objects you might create in a complex scene.


3

Step 4 – Add A Bevel Modifier To The Base Polygon

From the Modify tab click on Polygon icon in Selection rollout menu (keyboard shortcut “4”) and select the bottom polygon of the can object. Click the little box next to Bevel, change the Height amount to 2.0mm and the Outline to ‐2.0mm. Click the tick icon in the Bevel rollout to set the values.

Step 5 – Extrude Base Polygon

Now use the Extrude option on the same base polygon with an amount of 2.0mm. Remember to click the tick icon in the Extrude rollout to set the Extrude value.


4

Step 6 – Inset Base Polygon

Inset that base polygon with an amount of 1.0mm. Again, remember to click the tick icon in the rollout to set the Inset value this time.

Step 7 – Extrude Base Polygon Inside

Again, extrude the base polygon. This time change the amount to ‐2.0mm to push it inside a touch. Remember to tick that box again in the rollout to set the Extrude value.


5

Step 8 – Bevel Base Polygon

Bevel the base polygon now with a Height of ‐2.0mm and an Outline of ‐5.0mm. Don’t forget to tick the box in the rollout to set the Bevel value.

Step 9 ‐ Bevel Base Polygon Again

Bevel the base polygon again, only this time change the Height to ‐1.0mm. Leave the Outline to ‐5.0mm.


6

Step 10 – Inset The Base

With the same base polygon still selected, click the Inset button, change the inset amount to 5.0mm, click 2 times on the plus sign to apply the Inset twice, after that click on the tick mark for OK.

Step 11 – Change The Selection Mode To Vertex

To convert the selection to Vertex hold down the CTRL key and click on the Vertex icon. Note how you now have the corner points where the polygons are selected shown as red and all the other corner points of the can are blue.


7

Step 12 – Weld Vertices At Base Of Can

With the vertices resulted from the conversion selected, click on the Weld button and change the amount to 2.5mm. You will now see all the vertices snap together as one. This cleans up the geometry mesh. Good geometry mesh is known as ensuring you have sound mesh topology which is especially important should you animate an object by deforming the mesh.

Step 13 – Remove Every Second Edge To Keep 4 Sided Polygons

If you like press Alt+W to maximise the Perspective Viewport. Change the selection mode to Edge (keyboard shortcut “2”). Zoom into base area. Select every other edge by holding down Ctrl key and clicking on edges and click on Remove.


8

Step 14 – Create Edge Loop Selections

Make sure Edge mode is still selected. Select the highlighted two edges by Ctrl clicking and then click on Loop to make a loop selection of the 2 edges.

Step 15 – Chamfer Edges

Chamfer the selected edges with an amount of 0.25mm. Remember to tick the box to set the Chamfer value.


9

Step 16 – Create Another Loop Selection And Chamfer

Make an Edge Loop selection as we did in Step 14 on the edge shown below and Chamfer the edge with a setting of 1.0mm.

Step 17 – Bevel Top Of Can

Go to the top of the drink can select the top polygon (keyboard shortcut “4”). Apply a Bevel modifier with a Height to 2.0mm and an Outline of ‐2.0mm.


10

Step 18 – Extrude Top Of Can Twice

Extrude the same polygon twice with an amount of 2.0mm each time.

Step 19 – Inset Top Of Can

Inset the selection with an amount of 1.0mm.


11

Step 20 – Extrude Down Top Of Can To Create Lip

Extrude the selection with an amount of ‐3.0mm to push the top of the can down to create lip at top of can.

Step 21 – Inset The Inner Top Of Can

Inset the selection with an amount of 1.5mm.


12

Step 22 – Bevel The Inner Top Of Can

Bevel the selection with a Height of 1.5mm and an Outline of ‐0.5mm.

Step 23 ‐ Inset The Inner Top Of Can

Inset the polygon 2 times, first with an amount of 1.0mm and second with an amount of 10mm.


13

Step 24 – Push Inside Of Top Lip Of Can Out

To be more accurate with the modelling of our drink can we need to make the can "lip" a little bit thinner. So select the polygons you see selected below. Do this by Ctrl + clicking each one as you rotate the can object. Use the Selection Center option, right click on the Select and Scale tool, change the Offset: World to 103 and press Enter.

Step 25 – Extrude Outer Edge Of Top Lip

Now select the outer polygons using the Ctrl + click method and click on Extrude button. Change the extrusion type to Local Normals and the amount to 0.2mm.

What is a Normal? A “normal” is used in computer graphics to determine a surface's orientation. In this example it’s the

direction that a polygon is facing. [Ref: http://en.wikipedia.org/wiki/Normal_(geometry)]


14

Step 26 – Select Edges Of Top Lip Of Can

Make sure Edge mode is selected. Select the highlighted three edges shown below (zoom in to see them better) by Ctrl clicking and then click on Loop to make a loop selection.

Step 27 – Chamfer The Edges

Chamfer the 3 edges with a value of 0.1mm. Remember to click the tick to store the value of the Chamfer.


15

Step 28 – Edge Loop Select And Chamfer Upper Part Of Can

Make another edge loop selection as shown below and chamfer this with an amount of 1.0mm.

Step 29 – Scale The Inner Top Out A Touch

Select the top middle polygon to make a further adjustment to the top part of the can and press Grow 3 times to expand the selection. Scale the selected polygons using the Select and Scale tool to 105 in the X and Y axis direction.


16

Step 30 – Adjust Vertex Positions To Create Can Mouth Shape

Change to a Top View and enter Vertex selection mode (keyboard shortcut “1”). Turn on Ignore Backfacing so you do not pick any vertex points on the can base. Using the Select and Move tool arrange the vertices as shown below. You are aiming to create the can opening shape area.

Step 31 – Move Mouth Shape

Now select the polygon and move it down using the Select and Move tool in the Y direction to the position where it should be for the can opening.


17

Step 32 – Inset Mouth Shape

Inset the opening Polygon by 0.2mm.

Step 33 – Select The Inset

Click the Grow option once to expand the selection to include the new Inset polygons and the can opening. Now hold down the Alt key and click on the can opening polygon to de‐select this and leave just the surrounding polygons selected.


18

Step 34 – Form The Can Opening

Extrude the selected Polygons twice by ‐0.1mm to make the piece that forms the can opening. Here the viewport has been switched to Perspective (keyboard shortcut “P”).

Step 35 – Make A Ring Selection

In Edge selection mode select the edge you see selected below, then click on Ring to make a ring selection and after that click on Connect to connect the edges together. Here the viewport has been switched back to Top (keyboard shortcut “T”).


19

Step 36 – Move Vertex Points

Using the Select and Move tool move the vertices until you have something like below. Go to Vertex mode and enable Edge in Constraints. With this option enabled you can only move the vertices along the edges. Using the Select and Move tool move the vertices until you have something like below.

Step 37 – Extrude Edges To Make Drip Edge

Change the Constraints to None. Select the Edges shown below by Ctrl + clicking and Extrude them with a Height of 0.75mm and a Width of 1.25mm.


20

Step 38 – Remove Unnecessary Edges

Now select these two edges and Remove them by pressing the Remove button.

Step 39 – Apply A Turbosmooth Subdivision Surface Modifier

To finish the 3D modelling of the can from the Modify List add a Turbosmooth modifier and change the Iteration to 2. Check the box for Isoline Display. This finishes the 3D modelling part of the can. In the next 3D modelling steps of the guide we will create the opener for the can.


21

Step 40 – Freeze Can

Before commencing the ring pull part of the can, freeze the can object to prevent it being edited. Firstly, right‐click on the can object, click on Object Properties and then uncheck the Show Frozen in Gray option. Right‐click again and then left click on the Freeze Selection option to freeze the can object.

Step 41 – Create A Plane For Opening Mechanism For Can

In this part of the guide we will create the can opener. From Create > Geometry, create a Plane with the Length of 25mm and the Width of 15m. Change the Length segments to 4 and the Width segments to 2. Using the Select and Move tool position the plane right on top of the can as shown below. Name the new object. Here we have called it “ring pull”


22

Step 42 – Create Diagonal Cuts Across The Plane

Convert the Plane to Editable Poly. Right‐click the Snap icon and change the Snap setting to Endpoint. Select Edge selection mode and using the Cut tool make the cuts as shown below. Once complete turn off the Snaps Toggle

Step 43 – Chamfer The Vertices Where They Cross To Create Openings

In Vertex selection mode select the two vertices where the cuts cross shown below and Chamfer them with an amount 5.0mm.


23

Step 44 – Delete The Hexagon Polygons

Go to Polygon mode and delete the polygons resulting from the chamfer of the vertices as shown below.

Step 45 – Adjust Vertices To Create An Opening Shape

Arrange the vertices using the Select and Move/Select and Scale tool as shown below to create a suitable shape. You may need to drag a selection over a vertex and click the Weld option as there could be 2 vertexes overlaying each other as a result of creating the edge cuts.


24

Step 46 – Make Some Extra Cuts

In Edge selection mode make 4 new Cuts.

Step 47 – Use Shell Modifier To Add Height To Opener

Now add a Shell modifier from the Modify List, change the Outer Amount to 0.5mm and the number of Segments to 2.


25

Step 48 – Create New Edges For Anchor Point Of Opener

Convert the object to Editable Poly once again to collapse the modifier. In Edge mode click the Edge shown, then make a Ring selection and then click Connect.

Step 49 ‐

Select the 4 polygons shown below and Extrude them with an amount of around 10mm. The exact Extrude amount is dependent on the need to get close to the other side of the gap.


26

Step 50 – Add Polygons To Ring Pull Anchor Part

Make a Ring selection for the edges resulted from the extrusion of the polygons made in previous step. Click Connect with 1 segments and a Slide of 50. Don’t forget to click the tick to store the Connect values.

Step 51 – Apply Turbosmooth Subdivision Surface Modifier To Ring Pull

Add a Turbosmooth modifier from the Modify list and change the Iterations to 2. Check the box for Isoline Display.


27

Step 52 – Create Anchor Point For Ring Pull

The final step is to create another cylinder with a Radius of 2mm, Height of 0.5mm and Sides of 48. Using the Select and Move tool position as shown below.

The modelling of the can is now complete.

The next part will be applying the label and aluminium metal textures.
